What are you using to list keys? Are you using secondary indexes? You can get
all the keys for a bucket using the $bucket index, or do a range scan on $key.
See http://docs.basho.com/riak/latest/dev/using/2i/
<http://docs.basho.com/riak/latest/dev/using/2i/> . If your cluster is healthy
that should return the keys without throwing a timeout error.
Kind regards,
Timo
